    Red face fprintf data to string

    Hi all!

    I found a good source and I'm editing it.
    My only problem is that the source uses fprintf.
    Code:
    fprintf(file, "%d", i);
    How can I acces file data so I can parse it as string?
    Or convert file into a C-string?

    Thanks!

    So, you want the number output to a string, rather than a file, is that it?

    You can use "sprintf(str, "%d", i)" for that, if you like.

    Compilers can produce warnings - make the compiler programmers happy: Use them!

    I thought in that, but the thing is that uses something like this:
    Code:
    FILE *in = stdin, *out = stdout;
    in = fopen(pszFile, "rb");
    in = stdin;
    _setmode(_fileno(in), _O_BINARY);
    for (j = 0; j < sizeof signature; j++) {
         fprintf(out, hexfmt, signature[j]);
    }
    ///...
    BTW: Is md5 code that I found
